This directory contains some user-contributed builds of John the Ripper for
Linux. Please note that your other alternatives include: building JtR from
source on your own (easy and generally recommended to do on Linux), purchasing
JtR Pro, or using the "john" package provided by your Linux distribution (many
do, including Fedora, RHEL/CentOS, Debian, Ubuntu, Gentoo, and others - and
indeed Openwall). The functionality, performance, and dependencies of
different builds of JtR may differ (due to patches, build options, and build
systems). See also:

john-1.7.9-Linux-x86-32.tar.gz, john-1.7.9-Linux-x86-64.tar.gz,
john-1.7.9-jumbo-5-Linux-x86-32.tar.gz, john-1.7.9-jumbo-5-Linux-x86-64.tar.gz
are builds by Robert B. Harris. They're statically linked, including to
OpenSSL and to glibc. They require a Linux 2.6+ kernel.
Some RPM packages are by Simon John. They're intended for 64-bit Fedora 13 and
Fedora 14 (in fact, the Fedora 14 ones happen to work on Fedora 13 as well).
All of them include OpenMP parallelization for some of the hash types. Please
refer to Simon's posting to john-users for more detail:
